Candidate-reported interview process
It was a phone interview. It started with an introduction to the company, then they asked some probability questions. There was a technical part, and I was also asked to explain technical concepts to non-technical people.
It was a 30-minute phone call. Started with them introducing the company and what they're looking for in a candidate. Then, I had to solve a probability problem and explain it to a manager or others who aren't familiar with probability.
A few days after applying, I got a call for the first round. It was with a VP and lasted about 30 minutes. He started by talking about the company and the type of person they were looking for, then asked me some probability questions.
